AXLE.

SPECIFICATION forming part of Letters Patent No. 658,621, datedSeptember 25, 1900.

Application iiled August 3, 1900. Serial No. 25,789. (No model.)

T0 all whom, it may concern:

Be it known that LWILLIAM Cox DALZELL, a citizen of the United States,and a resident of South Egremont, in the county of Berkshire and Stateof Massachusetts, have invented a new and Improved Axle, .of which thefollowing is a full, clear, and exact de- 4scription.

This invention relates particularly to axles t'or vehicles in which theWheel-spindle swings on the axle, such as in automobiles; and the objectis to provide movable hard-metal bearings with a simple means foradjusting the same as they become worn.

I will describe an axle embodying my invention and then point out thenovel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of a portion of an axle embodying myinvention. Fig. 2 is a sectional side elevation thereof, andFig. 3 is asection on the line a; :n of Fig. 2.

Referring to the drawings, l designates a wheel-spindle having a hubportion 2, mounted to swing relatively to the axle 3. A kingbolt 4passes through lugs or ears 5 on the end of the axle, and thescrew-threaded lower vend of this king-bolt 4 engages with an interiorthread of a nut 7, having an exterior thread engaging in a tapped holein the ear or lug 6, and on the extreme outer end of the threadedportion of the king-bolt is a locknut S. The under side of the ear orlug 5 is provided with a recess 9, Within which a bearing-plate 10, ofhardened steel, is removably placed, and engaging with this plate lO isa hardened-steel bearing-plate ll, seated in a recess in the upper endot' the hub 2. A hardened-steel bearing-plate l2 is removably seated inthe recess in the lower end of said hub and engages with 'ahardened-steel bearing-plate 13, removably seated in a recess formed inthe inner side of the ear or lug 6, y

and this bearing-plate 13 is engaged by the nut 7, so that when theseveral bearing-plates wear the wear may be taken up by screwing the nut7, thus forcing the plate 13 up against the plate l2, and consequentlyraising the hub 2 so that the plate 11 will engage closely against theplate lO. The nut 7, therefore, not only serves for adjusting thebearings, but it also serves to hold or receive the kingbolt. Obviouslythese adjustments may be made when required without removing the wheelsof the vehicle or without removing the spindles from the axles, it beingonly neces, sary to remove the spindles when new bearing-plates are tobe placed in position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination with an axle and a spindle mountedto swing relatively thereto, of a hub portion for the spindle,hardenedmetal bearing-plates seated in recesses in the ends of thespindle, hardened-metal bearingplates seated in recesses formed in earsor lugs extended from the axle, a kingbolt extended through said ears orlugs and through the hub of the spindle, and a nut with which saidking-bolt engages, the said nut also serving to adjust the bearings,substantially as specified. f

2. An axle having outwardly-extended ears or lugs, hardened steelbearing-plates removably seated in recesses in the inner sides of saidlugs, a spindle having a hub portion,

hardened steel bearing plates removably seated in recesses formed in theends of said hub, a nut having an exterior thread engaging with athreaded opening in the lower ear or lug, a king-bolt passing throughthe ears or lugs and through the hub and engaging with an interiorthread ot' said nut, and a lock-nut, substantially as specified.

In testimony whereof I have signed my name to this speciication in thepresence of two subscribing witnesses.

WILLIAM COX DALZELL.
